    摘要: The present disclosure generally pertains to systems and methods for protecting network resources from denial of service attacks. In one exemplary embodiment, a responder stores an access filter value used to determine whether an incoming message frame has been transmitted from an authorized user. In this regard, a user communication device includes logic for determining the access filter value stored at the responder and, includes the access filter value in a message frame transmitted from the computer to the responder. The responder compares the received access filter value to the stored access filter value. If such values match or otherwise correspond, the responder authenticates the message frame. However, if such values do not match or otherwise correspond, the responder discards the message frame. Thus, the responder processes authenticated message frames and discards unauthenticated message frames thereby preventing denial of service attacks from malicious users.

    摘要: A system for preventing successful denial of service attacks comprises a first communication device, a second communication device, and a network. The first and second communication devices establish a communication session via the network. Based on various information, such as a pre-shared secret, one of the communication devices determines a network access filter value and compares this value to at least one data frame in order to authenticate such data frame without committing significant computing resource and any memory space. By updating the network access filter over time, an unauthorized user who discovers the outdated network access filter values is prevented from successfully launching a denial of service attack.

    摘要: A system for buffering data received from a network comprises a network socket, a plurality of buffers, a buffer pointer pool, receive logic, and packet delivery logic. The buffer pointer pool has a plurality of entries respectively pointing to the buffers. The receive logic is configured to pull an entry from the pool and to perform a bulk read of the network socket. The entry points to one of the buffers, and the receive logic is further configured to store data from the bulk read to the one buffer based on the entry. The packet delivery logic is configured to read, based on the entry, the one buffer and to locate a missing packet sequence in response to a determination, by the packet delivery logic, that the one buffer is storing an incomplete packet sequence. The packet delivery logic is further configured to form a complete packet sequence based on the incomplete packet sequence and the missing packet sequence.

    摘要: A unipolar terminal-attractor based neural associative memory (TABAM) system with adaptive threshold for perfect convergence is presented. By adaptively setting the threshold values for the dynamic iteration for the unipolar binary neuron states with terminal-attractors for the purpose of reducing the spurious states in a Hopfield neural network for associative memory and using the inner-product approach, perfect convergence and correct retrieval is achieved. Simulation is completed with a small number of stored states (M) and a small number of neurons (N) but a large M/N ratio. An experiment with optical exclusive-OR logic operation using LCTV SLMs shows the feasibility of optoelectronic implementation of the models. A complete inner-product TABAM is implemented using a PC for calculation of adaptive threshold values to achieve a unipolar TABAM (UIT) in the case where there is no crosstalk, and a crosstalk model (CRIT) in the case where crosstalk corrupts the desired state.
